摘要： PROBLEM TO BE SOLVED: To provide the optimum antenna structure for a wearable antenna.
SOLUTION: In an antenna wherein an antenna plane consists of a conductive plane, the antenna plane consisting of a conductive plane can spread out and the antenna plane consisting of a conductive plane is formed with a main slit having an open end opened to part of an edge of the conductive plane and a short-circuited end short-circuited by the conductive plane and a sub-slit which cuts across the main slit. The sub-slit has folded-back portions in the end parts close to edges of the conductive plane. Since the antenna plane consisting of the conductive plane can spread out, when the antenna is worn, for example, on clothes, the antenna plane consisting of the conductive plane spreads out in conformity with the body shape of a wearer and functions as an antenna and moreover, the wearer of the antenna feels a better sense of comfort with the antenna.
